I'm fine with that. Residential customers shouldn't be running DNS servers anyway and as far as the outside resolvers to go, ehhhh... I see the case for OpenDNS given that you can use it to filter (though that's easily bypassed), but not really for any others.
Except that half the time people run their own DNS resolvers because their provider's resolvers are 1) Absolute garbage and either fail queries for no reason, don't respond at times, respond super slow, etc. 2) Hijack NXDOMAIN for advertising / money generation 3) Hijack responses to inject their own ads, popups, etc. -- Brielle Bruns The Summit Open Source Development Group http://www.sosdg.org / http://www.ahbl.org
